As for dangling else - good idea, I added a text and example
mentioning it briefly at the of
http://michalis.ii.uni.wroc.pl/~michalis/modern_pascal_introduction/modern_pascal_introduction.html#_testing_if
.

As for "otherwise" in "case" - I admit I prefer the "else" keyword
there. Although I don't have any other argument for it than being
accustomed to it, from reading existing sources. I just grepped FPC
and Lazarus source code, and I couldn't find any "case" with
"otherwise" section... while I easily found occurrences of "case" with
"else" sections.

For this reason, I am inclined to keep the example with "case ..
else", not "case .. otherwise". Indeed, one needs to be more careful
then (to not mix the "else" with an "if" from the last statement).

That's a great analogy. I may steal it some day:)

Thanks! I improved it a bit, adding "the" at some places and changed
to sentence to simpler "Useful when a simple class inheritance is not
enough.".

I'm not a native English speaker, so any corrections and suggestions
are very welcome when it comes to the language (and everything else:)
